Abstract

A method and a system for adjusting a volume of a conference call are provided. The system includes at least one sub-device and a host. The host respectively connects the at least one sub-device and detects a number of the connected sub-devices. The host adjusts a volume of an original voice signal received from an external device according to the number of the connected sub-devices to generate an adjusted voice signal adapted to each sub-device and provides the same to each sub-device to play. The host also adjusts volumes of the original voice signals received by the host and each sub-device, integrates the adjusted original voice signals into an integrated voice signal adapted to the external device, and provides the same to the external device to play.

First claim

What is claimed is:

1 . A method for adjusting a volume of a conference call, adapted to adjust volumes of a host and at least one sub-device in the conference call, comprising:
respectively connecting the at least one sub-device, and detecting a number of the connected sub-devices by the host; receiving an original voice signal from an external device by the host; adjusting a volume of the original voice signal according to the number of the connected sub-devices by the host to generate an adjusted voice signal adapted to each of the sub-devices; and respectively transmitting the adjusted voice signal to the sub-devices to play by the host.

2 . The method as claimed in claim 1 , wherein the step of adjusting the volume of the original voice signal according to the number of the connected sub-devices by the host to generate the adjusted voice signal adapted to each of the sub-devices comprises:
inquiring a volume mapping table to obtain a volume threshold corresponding to the number of the sub-devices by the host; determining whether the volume of the original voice signal exceeds the volume threshold by the host; and decreasing the volume of the original voice signal according to the volume threshold by the host to generate the adjusted voice signal adapted to each of the sub-devices if the volume of the original voice signal exceeds the volume threshold.

3 . The method as claimed in claim 2 , wherein the step of decreasing the volume of the original voice signal according to the volume threshold by the host to generate the adjusted voice signal adapted to each of the sub-devices comprising:
decreasing the volume of the original voice signal to the volume threshold by the host to serve as the adjusted voice signal adapted to each of the sub-devices.

4 . The method as claimed in claim 2 , wherein the step of decreasing the volume of the original voice signal according to the volume threshold by the host to generate the adjusted voice signal adapted to each of the sub-devices comprising:
obtaining a decibel (dB) capable of being produced by a loudspeaker of each of the sub-devices by the host; and decreasing the volume of the original voice signal according to a proportion of the decibels of the sub-devices by the host to generate the adjusted voice signal adapted to each of the sub-devices.

5 . A method for adjusting a volume of a conference call, adapted to adjust volumes of a host and at least one sub-device in the conference call, comprising:
respectively connecting the at least one sub-device, and detecting a number of the connected sub-devices by the host; adjusting volumes of original voice signals received by the host and each of the sub-devices to generate adjusted voice signals according to the number of the connected sub-devices; integrating the original voice signals or the adjusted voice signals of the host and the sub-devices by the host to generate an integrated voice signal adapted to an external device; and transmitting the integrated voice signal to the external device to play by the host.

6 . The method as claimed in claim 5 , wherein the step of adjusting the volumes of the original voice signals received by the host and each of the sub-devices to generate the adjusted voice signals according to the number of the connected sub-devices comprises:
receiving the original voice signals of each of the sub-devices by the host; and adjusting the volumes of the original voice signals of the host and each of the sub-devices according to the number of the connected sub-devices by the host to generate the adjusted voice signals.

7 . The method as claimed in claim 6 , wherein the step of adjusting the volumes of the original voice signals received by the host and each of the sub-devices by the host to generate the adjusted voice signals according to the number of the connected sub-devices comprises:
inquiring a volume mapping table to obtain a volume threshold corresponding to the number of the sub-devices by the host; determining whether the volumes of the original voice signals of the host and each of the sub-devices exceed the volume threshold by the host; and decreasing the volumes of the original voice signals to the volume threshold by the host to generate the adjusted voice signals if the volumes of the original voice signals exceed the volume threshold.

8 . The method as claimed in claim 5 , wherein the step of adjusting the volumes of the original voice signals received by the host and each of the sub-devices to generate the adjusted voice signals according to the number of the connected sub-devices comprises:
transmitting the number of the connected sub-devices to each of the sub-devices by the host; and adjusting the volume of the original voice signal according to the number of the sub-devices to generate the adjusted voice signal, and transmitting the adjusted voice signal to the host by each of the sub-devices.

9 . The method as claimed in claim 8 , wherein the step of adjusting the volume of the original voice signal according to the number of the sub-devices by each of the sub-devices to generate the adjusted voice signal comprises:
inquiring a volume mapping table by each of the sub-devices to obtain a volume threshold corresponding to the number of the sub-devices; determining whether the volume of the original voice signal exceeds the volume threshold by each of the sub-devices; and decreasing the volume of the original voice signal to the volume threshold by each of the sub-devices to generate the adjusted voice signal if the volume of the original voice signal exceeds the volume threshold.

10 . A conference call volume adjusting system, comprising:
at least one sub-device; and a host, respectively connecting the at least one sub-device, and detecting a number of the connected sub-devices, wherein the host adjusts a volume of an original voice signal received from an external device according to the number of the connected sub-devices to generate an adjusted voice signal adapted to each of the sub-devices, and provides the adjusted voice signal to the sub-devices to play, and the host adjusts volumes of the original voice signals received by the host and each of the sub-devices according to the number of the sub-devices, integrates the original voice signals into an integrated voice signal adapted to the external device, and provides the integrated voice signal to the external device to play.

11 . The system as claimed in claim 10 , wherein the host inquires a volume mapping table to obtain a volume threshold corresponding to the number of the sub-devices, determines whether the volume of the original voice signal exceeds the volume threshold, and decreases the volume of the original voice signal according to the volume threshold to generate the adjusted voice signal adapted to each of the sub-devices if the volume of the original voice signal exceeds the volume threshold.

12 . The system as claimed in claim 11 , wherein the host decreases the volume of the original voice signal to the volume threshold to serve as the adjusted voice signal adapted to each of the sub-devices.

13 . The system as claimed in claim 11 , wherein the host obtains a decibel (dB) capable of being produced by a loudspeaker of each of the sub-devices, and decreases the volume of the original voice signal according to a proportion of the decibels of the sub-devices to generate the adjusted voice signal adapted to each of the sub-devices.
